This invention relates to apparatus for constructing buildings of molded material such as cement and pertains particularly to a structure for forming blocks of materialand for forming in set-upcondition hollow wall structures.

The primary object of this invention is to provide a structure by the use of ,Whicha complete building may be set-up from the foundation to the roof including floor and geiling joists and ceiling base built over false oor.

Another object of the invention is to provide a structure by which walls may be cast 1| having air spaces extending therethrough to all parts and having inner and outer bodies bonded together by webs of the cement of which the wall is constructed, the areas be- I tween the inner and outer bodies and between the bonding webs forming spaces for the circulation of air.

Another object of the invention is to provide a collapsible wall form having inner and outer form walls and central or core Walls with means for maintaining all of the walls in a predetermined relation for the formation of a cement wall of the character above described and further having the core walls transversely divided and so connected that a 80 collapsing of the core form will-take place when the elements of the structure are released from the fixed wall forini'ng position to be set-up in another position. a

Still another object of the invention is to provide an improved hollow brick or cast block forming structure having a collapsible central or core portion for facilitating the removal of the block from the form.

Other objects and advantages of the in vention will become apparent as the description of the same proceeds and the invention will be best understood from a con-. sideration of the following detailed description taken in connection with the accompanying drawings forming a part of the present invention with the understanding, however, that theinvention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so 59 long as such changes or modifications mark iidinaterial departure from thesalient features of the invention as expressed in the appended claims.

Referring more particularly to the drawings wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates generally the present hollow block or brick forming structure embodying a part of the present invention which structure, as shown, is designed for moldin at one operation, a plurality of hollow b ocks preferably 24" lon 8'-' wide and 107' high though, of course, wish it to be understood that I do not want to be limited to the structure for forming blocks of this size only as it will be obvious that a brick of any size-may be formed.

The brick casting form comprises a base 2 provided with longitudinally extending walls 3 which are spaced 51 art a distance ua'lto the length of the bloc s, thatis ap roxlmate- 1y 2 Running transversely o the longithe entire structure to fill 1 Each end 'in set position. In this structure which comprises a. rigid back wall 6 which extends lengthwise of the formed block, a shiftable forward wall 7 which is designed to move toward or away from the wall 6 and end walls 8.

As is shown, the four walls 6, 7 and form a rectangular core and when set-up a block is formed by filling the spaces between these walls and the them with the cement or other plastic material.

Each of the end walls 8 of the block core structure is turned at an angle as indicated at 9 and one ofthese angled ends of each end wall is hingedly connected as indicated at 10 to the adjacent end of the stationary wall 6. of the shiftable wall 7 is also angled as indicated at 11 and when the core is assembled for the formation of a block, the angled free end of each end wall is swung to osition against the adjacent angled end 0 the shiftable wall so that the end walls maintain the shiftable wall in spaced relation with res ect to the fixed wall 6.

sprin 12, or if found desirable'a rubber body may used in this position, is stretched between the walls 8 are swung in to collapse the block core the shiftable wall 7 will be drawn in also permittin the easy removal of the block. J

Each 0 the block core structures is covered or closed by a top .13 u on the underface of which at each corner t ere is secured a deending resilient arm or bracket 14 which rictionally enages the inner face of an angled corner of the core to maintain the top in position.- It will thus be seen that with a number of the cores set-up and each covered by a top 13, cement may be poured over all of the forms without danger of getting any of the material in the cores thereof.

In Figures 6 to 11 there is shown the structure provided for the casting or molding of building walls and other units of a building forming structure there are provided inner and outer form walls 15 and 16. respectively and center or core forms each indicated as a whole by the numeral 17 each of which walls 18 which when set-u are arranged in spaced parallel relation with the innerand outer form walls in the manner shown.

' ese pairs of core walls-18 are formed at each end edge to extend obliquelyof the formed wall, as indicated at 19 and are connected by the heavy resilient webs 20 which are preferably constructed of rubber of suitpartltions 4 and 5 surrounding f 25, which legs are preferabl walls 6 and 7 so that when the illustrated in Figures 6 to comprises a pair ofable weight, these webs being secured to the .core wallsin any suitable manner.

. ner and outer form walls in the proper position, there are provided anumber of holding devices each of which is here indicated generally by thenumeral 21.

Each of these holding devices consists of a pair of beams 22' and 23 one of which, as for example the beam 22, is pivotally attached at one end, as at 24, to the other beam at a point inwardly of one end thereof, which end or convenience in describing-this device will be referred to as the forward end.

Each of these beams 22 and 23, of each holding member carries a pair of depending legs formed, as are also the beams 22 and 23, of s eet iron. Each of the legs 25 is adj ustably attached to its supa series ofsuitably positioned apertures 27 r to facilitate the adJustment of the legs thereon and longitudinally thereof so as to enable the-user to arrange the'form walls for the construction of thick or thin building walls, as desired.

Each of the legs 25 of one beam, as for example, the beam 23, has an edge thereof provided with a lateral flange 28 each designed to oppose a similar flange 28 formed along one edge of theadjacent leg of the other beam.

As shown in Figures 6 and 8, one leg of one beam engages 'andis secured to one ofthe form walls 15 or 16 while the other leg thereof engages and is secured to one of the walls 18 of the core structure so that a clear space is left between the walls of the core structure and the legs maintain all of the walls in the desired position so that cement may be placed between the inner'and outer form walls and the core walls, as will be readily understood.

The type of form most frequently used is 11, this type being employed for adding sections or units to the building'wall after the first section has been formed. In this type the walls of the form do not extend to the bottom of the legs 25 but terminate a substantial distance thereabove and, as is shown in Figure 8, each leg carries upon the face of the flange 29, below the wall, a rubber foot or button 25 which projects slightly beyond the plane of the wall face.

The rear ends of the beams 22 and 23 of each of the form wall holding members are extended and are connected together by means of an operating latch structure which includes an arm 30 pivotally attached at one end as at 31 to one of the beams and having pivotally attached thereto as at 32, inwardly of its pivot point 31, one end of a link 33 structure is indicate meral 35 and comprises a above the other beam thus causing the legs 25 thereof and the walls carried thereby to swing away from the legs and walls of the other beam so that the space between the opposing flanges of the legs of the two beams W111 be increased to permit the wall forms to be removed from position. It will, of course, be readily seen that a reversal of the operation of the latching structure between the beams will bring the same back to parallel position so that the opposing walls carried by the flanges of the legs will be arranged in substantially parallel relation to maintain the form walls in place.

When the center two legs of each of the holding members are in position between the walls 18 of the core structure and the holdmember latched in operative position, the the core walls 18 mg resilient webs between will be expanded slightly so that whenthe form wall holding members are released these webs will contract and collapsethe wall a1r space forming cores 17;

In order to prevent the weight of the ce-' ment collapsing the webs 20 between the walls 18 of each core structure there is provided a reinforcing structure which connects the adjacent ends of the core structures and holds the webs thereof ri ids This reinforcing f as a whole by the nupair of planks 36 of substantially the same width as the webs 20 hi'ngedly connected together at one end as at 37 by a suitable resilient material such as belting material or leather. At the other ends these planks are connected by a suitable latch 38, which is pivotally attached to one plan'k t space between the webs of the cores which and has the other end turned for frictional engagement'overthe other plank as shown in gure 9. When the forms described areused for continuing the formation of a previously formed wall section they are so setp upon the previous wall section as to edges of the walls 15, 16, and 18 upon the top of the previously formed wall, the rubber feet or buttons engagin the adjacent face of the walls as shown in igure 8.

The beams 22 and 23 are. hen brought into )arallel relation in the manner previously de-- scribed and held by swinging the latch arm downwardly to the position shown in Figure 8. This action presses the feet or buttons 25' against the previously formed wall section thus holding the form securely in place.

ranged in position so that one plank of each of these structures will overlie the inner face of a web 20, the structure straddling the rrange the loweradapted to enter portion of the wallsof the "adjacent unit inthey connect, as shown in Figure 9. The upper ends of the planks are then drawn together and connected by the latch 38 so that the planks will be held in-substantially paral lel relation and will maintain the ad]acent webs of the cores sufliciently rigidto prevent their collapsing when the cement is poured in between the walls and between the webs.

y In starting the wall, forms ofsubstan- I tially the same construction as those shown and described are employed with the exception of the fact that the walls 15, 16,, and 18 are continued downwardly to the ends of the legs 25 to which the'y'are attached, the buttons 25 being, of course, done away with. Also. in the forming of the first wall unit the holding members for thewebs of the adjacent cores condition and the free lower ends are drawn together to proper position by passing wires about the planks below the hinge connection 27 therebetween. to bring the height of the wall up to a point adjacent the wires connecting the members 35 and after the pouredwall has been set the holding,wires may be released and the reinforcing structures 35 removed with the form. In this manner a low starting wall may be formed, which wall is indicated by the numeral 39. From the foregoing description it will be readily seen that the form walls 15, 16 and 18 may be easily and quickly- 'unit with an off-set portion 40 having a pluare put into place in inverted The cement is then poured rality of longitudinally extending apertures therethru, while the other side edge of said wall of the unit is provided with a series'of outwardly projectmg' pins 41 which ,are the apertures of the off-set the manner shown in Figure 12.

In the use of the building set described his necessary that the brick forming structure be used in association vwith the wall forming structure for building operations as loose brick or broken brick is often needed to fill in. partitions along small rooms .or closets where the wall molding form cannot be'emgloved.
